My experience has come from the raising the wildest, crazy puppy. Five year later and lots of obedience training, I would not trade it for anything. My dog is a 70-pound pit bull. So I have experience with bigger dogs and dogs that unfortunately carry the "aggressive breed" stigma. Even though pit bulls hold a special place in my heart, I love any and all dogs. My availability is mainly 5 pm or later during the week. However, depending on the week, I am available by 3 pm. I will work with you to try to find the time that works best for you and your companion. If your dog likes to go on runs, I will most certainly go on a jog with them.
